ROLLER BEARING.

Application tiled May 19,

This invention relates to roller bearings.

lt relates particularly to roller bearings for vehicle wheels.

An object of the invention is to provide an improved roller bearing which is efficient, durable, and which may be economically manufactured and easily assembled.

Another object is 'to provide an improved roller bearing having a large bearing surface for the rollers. Other objects and ad vantages will hereinafter appear.

For the purpose of illustrating the invention, an embodiment thereof is shown in the drawings, in which:

Figure 1 is a longitudinal central section through the bearing;

F ig. 2 is an end elevation looking toward the right in Fig. 1;

Fig. 3 is a perspective of the retainer-for the rollers;

Fig. 4 is a longitudinal central modified form; and

Fig. 5 is a longitudinal central section of a modified form.

The inventioncomprises in general, a tubular casing or shell 1, a cup-shaped retainer 2 for the rollers, and a tubular sleeve or spacer 3 fitted within the casing to hold the retainer in osition therein. 'The several elements speci ed are preferably formedl of' sheet metal so as to function as indicated by the drawings and as hereinafter described.

The cup-shaped retainer 2 comprises a ci rcular rim 4 which fits snugly although rotatably within the casing l and lugs' extending transversely thereto to provide circular openingsG for the rollers 7.'

The shell or casing l may be made from tubing and slit longitudinally, as shown at 8, to insure a-close non-rotative fit between the casing and the spacer 3. The inside diameter of casing l may be made slightly less than the outside diameter of the spacer 3 so that the casing will be sprung slightly when the spacer is inserted therein. A Snug fit between the shell and spacer is thereby effected.

The spacer 3may likewise be made from tubing and slit longitudinally, as shown at 9. The spacer will then contract slightly upon being` inserted into the casing l and will press outwardly against the same when in assembled relation with respect thereto.

In the embodiment of my invention, as shown in Fig. 1, a retainer 2 is slipped into the casing l and a spacer 3 inserted into section of a 1924. serial No. 714,272;

either end thereof to engage each side of the retainer and hold the same securely in position within the casing.

The spacers 3 are made from material of greater thickness than that used for the rim 4 of the retainer, as shown in Fig. 1. The rollers 7 will then bear upon the inner sur- -facesof the spacers 3 instead of the inner 'surface of the rim 4 or the bottom of the openings 6 when they are pressed radially outwardly by a shaft 10. A large bearing 'surface for the rollers is thereby provided.

lVhen the wheel to which the bearing is applied rotates about the shaft 10, the roll# ers 7 will roll upon the sleeves or spacers 3.

In themodiication shown in Fig. 4, a spacer 3 is fitted into the casing 1 and a retainer 2 inserted into either end of the casing to engage the spacer, the retainers facing inwardly. The spacer 3 thereby holds the two retainers in proper spaced relation with respect to each other within the casing.

The thicknessl of spacer 3 is made thicker than the rims '4' of theretainers, as shown, so that thelrollers 7 will bear upon the spacer. l

-In the modification shown in Fig. 5, the parts are asseiibled in the same manner shown in Fig. 4, but the retainers 2' face outwardly. This arrangement'niay be necessary in some cases, where there would be a slight longitudinal shifting of the rollers with respect to the casing, to prevent the ends of the rollers from slipping out of engagement with the lugs 5.

The casing 1 and spacers 3 may be solid tubes instead of being slit`longitudinally.

It will be observed that the cage for the bearing rollers constitutes means for spacingthc rollers apart from one another and also as a rotative carrier for the rollers which will also have a`rolling Contact with the .sleeve lining of the \casing in the rotation of the spacing carrier.-

Various changesv of structure may be adopted without departing from the spirit v of the invention as defined by the claims. The inventionblaimed is: l. A roller-bearing comprising a tubular member. a sleei'e spacer member positioned Y vithin the tubular member to form a recess between vcontiguous portions of the tubular member and sleeve member and constitute a lining to the tubular memberthroughout its) ma or portion from its middle towards bot-b ends, a cage member rotatively mounted in said recess, and roller-bearings mounted in tbe cage for rolling Contact with the inner surface of tbe sleeve member and carried by the cage in its rotation in its recess.

2. A. roller-bearing comprising a tubular member, a sleeve spacer member positioned within the tubular member to form a recess between contiguous portions of the tubular member and sleeve member, et least one of said members being slitted "for holding the two members in non-rotative relation to each other, a. means for spacing roller bearings and 35 rotatively mounted in said recess, and rollerbearings carried by said spacing means for rolling Contact with the inner surface of the sleeve member.

3. A roller-bearing comprising a. Sheet,- metal casing, a sheet-metal sleevedining to the casing, means formed of Sheet-metal for spacing n'iller-lierings apart from one anl other and rotatively mounted in the casing, and roller bearings carried by said rotative spacing means and in rolling Contact with the inner surface of tbe sleeve-lining.

In witness whereof i have hereto aflixed my signature.
